  • the known device for winding and unwinding sheet-shaped sealing elements is problematic in practice.

Description

Die Erfindung betrifft eine Vorrichtung zum Auf- und Abwickeln von bahnenförmigen Dichtungselementen, insbesondere von mit Schlössern versehenen Folien, mit einer drehbar gelagerten Wicklungshalterung.The invention relates to a device for winding and unwinding sheet-shaped sealing elements, in particular foils provided with locks, with a rotatably mounted winding holder.

Eine Vorrichtung der in Rede stehenden Art ist bereits aus dem deutschen Dokument DE-A-35 40 270 bekannt. In dieser Druckschrift wird ein Verfahren zur Herstellung einer Dichtwand und eine Vorrichtung zur Durchführung dieses Verfahrens beschrieben. Dabei werden Kunststoffbahnen von nur geringer, eigener Steifigkeit als Dichtungselemente auf rahmenartige Trageelemente aufgespannt. Die Dichtungselemente werden zusammen mit den Trageelementen mit Hilfe einer Hubvorrichtung in einen Erdschlitz abgesenkt, der mit einer sich verfestigenden Suspension gefüllt ist. Unter anderem wird in dieser Druckschrift auch eine Verfahrensvariante beschrieben, bei der die Kunststoffbahn endlos auf einer Rolle als Wicklungshalterung aufgewickelt ist, die seitlich neben dem Erdschlitz gelagert ist. Das untere Ende der Kunststoffbahn wird an einem, über dem Erdschlitz von der Hubvorrichtung gehaltenen Trageelement befestigt und mit dem Trageelement in den Erdschlitz abgesenkt, wobei sich die Kunststoffbahn von der Rolle abwickelt. Nach dem Erreichen der Solltiefe der Kunststoffbahn im Erdschlitz wird diese von der Rolle getrennt.A device of the type in question is already known from German document DE-A-35 40 270. This document describes a method for producing a sealing wall and an apparatus for carrying out this method. Plastic sheets of low rigidity of their own are stretched as sealing elements onto frame-like support elements. The sealing elements are lowered together with the support elements with the aid of a lifting device into an earth slot which is filled with a solidifying suspension. Among other things, this document also describes a method variant in which the plastic web is wound endlessly on a roll as a winding holder, which is mounted on the side next to the earth slot. The lower end of the plastic sheet is attached to a support element held above the earth slot by the lifting device and lowered into the earth slot with the support element, the plastic sheet being unwound from the roll. After reaching the desired depth of the plastic sheet in the earth slot, it is separated from the roll.

Die bekannte Vorrichtung zum Auf- und Abwickeln von bahnenförmigen Dichtungselementen ist jedoch in der Praxis problematisch. Bedingt durch die Materialeigenschaften der Dichtungselemente, insbesondere bedingt durch deren Abmessungen und Biegesteifigkeit, weist die bekannte Rolle einen relativ großen Durchmesser und eine große Breite auf und ist entsprechend schlecht transportierbar und manövrierbar. Die Rolle muß möglichst genau parallel zum Erdschlitz ausgerichtet sein, um auch die Dichtungselemente möglichst parallel zur Orientierung des Erdschlitzes anordnen zu können. Bei der bekannten Rolle ist diese Ausrichtung sehr aufwendig, da die Rolle mittels einer Hubvorrichtung oder einer anderen geeigneten Transportvorrichtung bewegt werden muß. Außerdem läßt sich die Position der Rolle nur sehr umständlich während des Absenkens des Dichtungselements in den Erdschlitz korrigieren.The known device for winding and unwinding sheet-shaped sealing elements is problematic in practice. Due to the material properties of the sealing elements, in particular due to their Dimensions and bending stiffness, the known roll has a relatively large diameter and a large width and is accordingly difficult to transport and maneuverable. The roller must be aligned as precisely as possible parallel to the earth slot so that the sealing elements can also be arranged as parallel as possible to the orientation of the earth slot. In the known roller, this alignment is very complex since the roller must be moved by means of a lifting device or another suitable transport device. In addition, the position of the roller can only be corrected with great difficulty during the lowering of the sealing element into the earth slot.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zum Auf- und Abwickeln von bahnenförmigen Dichtungselementen zu schaffen, die konstruktiv einfach und bequem in der Handhabung ist. Insbesondere soll die erfindungsgemäße Vorrichtung möglichst mobil sein, und zwar im Hinblick auf den Transport und das Manövrieren der Vorrichtung selbst und den Transport von bahnenförmigen Dichtungselementen zumindest im Baustellenbereich.The present invention is therefore based on the object of providing a device for winding and unwinding sheet-shaped sealing elements which is structurally simple and convenient to use. In particular, the device according to the invention should be as mobile as possible, specifically with regard to the transport and maneuvering of the device itself and the transport of sheet-like sealing elements, at least in the construction site area.

Die erfindungsgemäße Vorrichtung löst die voranstehende Aufgabe durch die Merkmale des Schutzanspruchs 1. Danach ist die Vorrichtung zum Auf- und Abwickeln von bahnenförmigen Dichtungselementen als Fahrzeug ausgebildet und umfaßt ein Fahrwerk. Die Wicklungshalterung bildet einen Oberaufbau des Fahrzeugs, so daß die Vorrichtung zumindest im Baustellenbereich zum Transport von Dichtungselementen einsetzbar ist.The device according to the invention achieves the above object by the features of the protection claim 1. Thereafter, the device for winding and unwinding sheet-shaped sealing elements is designed as a vehicle and comprises a chassis. The winding holder forms a superstructure of the vehicle, so that the device can be used at least in the construction site area for the transport of sealing elements.

Es ist erkannt worden, daß die Wicklungshalterung in vorteilhafterweise als Fahrzeugaufbau ausgebildet sein kann und so mit Hilfe des Fahrzeugfahrwerks einfach bewegt und an geeigneter Stelle positioniert und ausgerichtet werden kann. Die erfindungsgemäße Vorrichtung ermöglicht außerdem auf einfache Weise das Korrigieren der Position der Wicklungshalterung während des Absenkens des Dichtungselements in einen Erdschlitz. Dazu sind keine zusätzlichen Vorrichtungen erforderlich, die den eigentlichen Absenkvorgang behindern könnten. Ein weiterer wesentlicher Vorteil der erfindungsgemäßen Vorrichtung besteht darin, daß sie nicht nur in Verbindung mit dem eigentlichen Absenkvorgang verwendet werden kann, sondern auch zum Transport des Dichtungselements im Baustellenbereich. Üblicherweise werden Materialbahnen von nur geringer Steifigkeit, sogenannte Folien, als Dichtungselemente verwendet, die erst im Baustellenbereich auf die erforderliche Länge zugeschnitten werden. Die Folien werden dann an ihren seitlichen Rändern mit Schlössern versehen, beispielsweise durch Anschweißen von geeigneten Profilen. Die Bearbeitung der Dichtungselemente erfolgt üblicherweise an einem eigens hierfür vorgesehenen Ort im Baustellenbereich, jedoch nicht zwangsläufig in unmittelbarer Nähe des Einsatzortes der Dichtungslemente. Die erfindungsgemäße Vorrichtung ermöglicht nun das Aufwickeln der bahnenförmigen Dichtungselemente am Bearbeitungsort und den Transport zum Einsatzort, d. h. zum Erdschlitz, in den das Dichtungselemente abgesenkt werden soll. In Anbetracht der möglichen Längen von Dichtungselementen von bis zu 40 m stellt dies eine wesentliche Vereinfachung beim Erstellen von Dichtwänden dar.It has been recognized that the winding holder can advantageously be designed as a vehicle body and can thus be easily moved with the aid of the vehicle chassis and positioned and aligned at a suitable point. The device according to the invention also enables the position of the winding holder to be corrected in a simple manner while the sealing element is being lowered into an earth slot. This does not require any additional devices that could hinder the actual lowering process. Another important advantage of the device according to the invention is that it can be used not only in connection with the actual lowering process, but also for transporting the sealing element in the construction site area. Material webs with only low rigidity, so-called foils, are usually used as sealing elements, which are only cut to the required length in the construction site area. The foils are then provided with locks on their lateral edges, for example by welding suitable profiles. The processing of the sealing elements usually takes place at a specially designated location in the construction site area, but not necessarily in the immediate vicinity of the location of the sealing elements. The device according to the invention now enables the web-shaped sealing elements to be wound up at the processing location and transported to the place of use, ie to the earth slot into which the sealing element is to be lowered. Considering the possible lengths of sealing elements of up to 40 m, this represents a significant simplification when creating sealing walls.

Die aus dem deutschen Dokument DE-A-35 40 270 bekannte Vorrichtung zum Auf- und Abwickeln von bahnenförmigen Dichtungselementen ist auch deshalb in der Praxis problematisch, da eine Rolle generell nicht angetrieben ist und lediglich als Umlenkelement dient. Eine Rolle ist daher sowohl zum Aufwickeln von bahnenförmigen Dichtungselementen an einem Bearbeitungsort als auch zum Transport des aufgewickelten Dichtungselements und zum gezielten und gesteuerten Einbau des Dichtungselements in einem mit einer sich verfestigenden Suspension gefüllten Erdschlitz nur bedingt geeignet.The device for winding and unwinding sheet-shaped sealing elements known from German document DE-A-35 40 270 is also problematic in practice because a roller is generally not driven and only serves as a deflection element. A roll is therefore only suitable to a limited extent both for winding web-shaped sealing elements at a processing location and for transporting the wound sealing element and for the targeted and controlled installation of the sealing element in an earth slot filled with a solidifying suspension.

Der vorliegenden Erfindung liegt daher auch die Aufgabe zugrunde, eine Vorrichtung zum Auf- und Abwickeln von bahnenförmigen Dichtungselementen zu schaffen, mit der ein gezieltes Auf- und Abwickeln von bahnenförmigen Dichtungselementen möglich ist.The present invention is therefore also based on the object of providing a device for winding and unwinding sheet-shaped sealing elements, with which a targeted winding and unwinding of sheet-shaped sealing elements is possible.

Die erfindungsgemäße Vorrichtung löst die voranstehende Aufgabe durch die eingangs genannte Vorrichtung zum Auf- und Abwickeln von bahnenförmigen Dichtungselementen, die ferner so ausgestaltet ist, daß die Wicklungshalterung über einen reversierbaren Antrieb, d.h. einen Antrieb mit rechts/links-Lauf, verfügt.The device according to the invention achieves the above object by the above-mentioned device for winding and unwinding sheet-shaped sealing elements, which is further configured so that the winding holder via a reversible drive, i.e. a drive with right / left running.

Erfindungsgemäß ist erkannt worden, daß die Funktionalität einer Wicklungshalterung durch einen Antrieb im wesentlichen gegenüber der Funktionalität einer Rolle, die lediglich als Umlenkelement dient, erhöht werden kann. Die Wicklungshalterung kann je nach der Antriebsrichtung sowohl zum aktiven Aufziehen eines Dichtungselements auf die Wicklungshalterung eingesetzt werden, als auch zum gezielten und gesteuerten Einbau des Dichtungselements in den Erdschlitz.According to the invention, it has been recognized that the functionality of a winding holder can be increased by a drive essentially compared to the functionality of a roller, which serves only as a deflection element. Depending on the drive direction, the winding holder can be used both for actively pulling a sealing element onto the winding holder and for the targeted and controlled installation of the sealing element in the earth slot.

In einer besonders vorteilhaften Ausgestaltung der erfindungsgemäßen Vorrichtung nach Anspruch 1 ist der Oberaufbau des Fahrzeugs, d. h. die Wicklungshalterung, bezüglich der Position des Fahrwerks horizontal verschiebbar. Die Wicklungshalterung kann dabei lateral, d. h. beispielsweise in zwei zueinander senkrechten Richtungen in einer Ebene verschiebbar sein oder auch um eine Achse senkrecht zu dieser Ebene verdrehbar sein. Auf diese Weise läßt sich die Wicklungshalterung besonders einfach und exakt ausrichten, ohne daß das Fahrwerk der erfindungsgemäßen Vorrichtung über Grund bewegt werden muß. Dies ist insbesondere im Baustellenbereich vorteilhaft, wo keine homogene Fahrbahn zu erwarten ist. Hier erfordert das Manövrieren der gesamten Vorrichtung mit Hilfe des Fahrwerks besondere Geschicklichkeit, da die Reaktion des Fahrwerks nicht nur von der Steuerung und dem Antrieb des Fahrzeugs abhängt, sondern auch von der lokalen Bodenbeschaffenheit. Eine horizontale Verschiebung des Oberaufbaus des Fahrzeugs bzw. der Wicklungshalterung kann auf einfache Weise mit Hilfe von mindestens einem, im wesentlichen horizontal bewegbaren, inbesondere verschiebbaren und/oder drehbaren, Träger erfolgen, über den der Oberaufbau mit dem Fahrwerk verbunden ist.In a particularly advantageous embodiment of the device according to the invention, the superstructure of the vehicle, i. H. the winding bracket, horizontally displaceable with respect to the position of the chassis. The winding holder can laterally, i. H. for example, be displaceable in two planes perpendicular to each other or rotatable about an axis perpendicular to this plane. In this way, the winding holder can be particularly easily and precisely aligned without the chassis of the device according to the invention having to be moved over the ground. This is particularly advantageous in the construction site area, where a homogeneous roadway is not to be expected. Here, maneuvering the entire device with the help of the chassis requires special skill, since the reaction of the chassis depends not only on the control and drive of the vehicle, but also on the local ground conditions. A horizontal displacement of the superstructure of the vehicle or of the winding holder can be carried out in a simple manner with the aid of at least one, essentially horizontally movable, in particular displaceable and / or rotatable, carrier, via which the superstructure is connected to the chassis.

Um nun die Standfestigkeit einer, mit einem verschiebbaren Oberaufbau versehenen erfindungsgemäßen Vorrichtung zu erhöhen, wird vorgeschlagen, mindestens eine, vorzugsweise vier horizontale und vertikale ausfahrbare Abstützeinrichtungen vorzusehen. Diese Abstützeinrichtung kann die mit der Verschiebung des Oberaufbaus einhergehende Verschiebung des Schwerpunkts der erfindungsgemäßen Vorrichtung abfangen. Die Abstützeinrichtung dient aber auch zur Erhöhung der Standfestigkeit beim Abwickeln der Dichtungselemente, die üblicherweise mit Hilfe von Trageelementen in den Erdschlitz gezogen werden.In order to increase the stability of a device according to the invention provided with a displaceable upper structure, it is proposed to provide at least one, preferably four horizontal and vertical extendable support devices. This support device can intercept the shift in the center of gravity of the device according to the invention associated with the shift of the superstructure. However, the support device also serves to increase the stability when unwinding the sealing elements, which are usually pulled into the earth slot with the aid of support elements.

In einer besonders vorteilhaften Ausführungsform der erfindungsgemäßen Vorrichtung sind die Abstützeinrichtungen mit beweglich angelenkten Fußstücken versehen. Diese meist tellerartig ausgebildeten Fußstücke ermöglichen eine Anpassung der Standfläche an etwaige Bodenunebenheiten und Inhomogenitäten.In a particularly advantageous embodiment of the device according to the invention, the support devices are provided with movably articulated foot pieces. These mostly plate-like foot pieces allow the stand area to be adapted to any unevenness in the floor and inhomogeneities.

Besonders vorteilhaft ist es nun, wenn die erfindungsgemäße Vorrichtung zerlegbar ausgebildet ist. Dazu wird vorgeschlagen, daß der Oberaufbau, also die Wicklungshalterung vom Fahrwerk abnehmbar ist. Dies ermöglicht einen Transport der erfindungsgemäßen Vorrichtung mit herkömmlichen Transportmitteln. Das Fahrwerk, das in einer baustellengerechten Ausführungsform durch das Fahrwerk eines Kettenfahrzeugs gebildet ist, ist gewöhnlich nicht auf öffentlichen Straßen zugelassen und muß daher transportiert werden.It is particularly advantageous if the device according to the invention is designed to be dismantled. For this purpose, it is proposed that the superstructure, ie the winding holder, can be removed from the chassis. This enables the device according to the invention to be transported using conventional means of transport. The undercarriage, which in a construction site-specific embodiment is formed by the undercarriage of a tracked vehicle, is usually not permitted on public roads and must therefore be transported.

In einer besonders vorteilhaften Ausgestaltung der erfindungsgemäßen Vorrichtung ist der Antrieb der Wicklungshalterung steuerbar und/oder regelbar, wozu vorzugsweise ein Computer oder eine speicherprogrammierbare Steuerung vorgesehen ist. Auf diese Weise kann auch komplizierten Betriebsparametern Rechnung getragen werden, die beispielsweise in Verbindung mit dem Einbauverfahren auftreten. Beim Einbau eines Dichtungselements in einen mit einer abbindenden Suspension gefüllten Erdschlitz wirken veränderliche Kräfte auf das Dichtungselement ein. Das Dichtungselement kann beispielsweise auf Grund der Gewichtskraft eines am unteren Rand des Dichtungselements befestigten Trageelements in den Erdschlitz gezogen werden.In a particularly advantageous embodiment of the device according to the invention, the drive of the winding holder can be controlled and / or regulated, for which purpose a computer or a programmable logic controller is preferably provided. In this way, complicated operating parameters can also be taken into account, which occur, for example, in connection with the installation process. When installing a sealing element in an earth slot filled with a setting suspension, variable forces act on the sealing element. The sealing element can, for example, be pulled into the earth slot due to the weight of a support element attached to the lower edge of the sealing element.

Ist das Trageelement aus mehreren Teilstücken zusammengesetzt, so verändert sich die Gewichtskraft in Abhängigkeit von der Anzahl der Teilstücke. Zusätzlich wirken Scherkräfte bedingt durch die im Erdschlitz befindliche Suspension auf das Dichtungselement, die wiederum von der Einbringtiefe abhängen. Besonders vorteilhaft ist es nun, wenn die angetriebene Wicklungshalterung während des Einbauvorgangs immer eine Rückholkraft auf das Dichtungselement ausübt, die gerade so groß ist, daß das Dichtungselement straff im Erdschlitz gehalten ist, und gegebenenfalls erhöht werden kann, so daß das Dichtungselement zumindest stückweise wieder aus dem Erdschlitz gezogen werden kann. Dies erleichtert das Einfädeln von Schloßteilen benachbarter Dichtungselemente.If the support element is composed of several sections, the weight changes depending on the number of sections. In addition, shear forces act on the sealing element due to the suspension in the earth slot, which in turn depend on the insertion depth. It is particularly advantageous if the driven winding holder always exerts a return force on the sealing element during the installation process, which is just large enough that the sealing element is held taut in the earth slot, and can optionally be increased, so that the sealing element is at least partially removed again the earth slot can be pulled. This makes it easier to thread lock parts of adjacent sealing elements.

Von besonderem Vorteil ist es, wenn der Antrieb mindestens einen Motor in Verbindung mit einem nachgeschalteten Untersetzungsgetriebe umfaßt, so daß eine gute Kraftübertragung gewährleistet ist. Verfügt der Antrieb zusätzlich über eine Freilaufschaltung, so daß die Wicklungshalterung auch als Drehlagerung für Dichtungselemente verwendbar ist, so kann die Wicklungshalterung auch als reines Umlenkelement fungieren.It is particularly advantageous if the drive comprises at least one motor in conjunction with a downstream reduction gear, so that good power transmission is ensured. If the drive also has a free-wheeling circuit so that the winding holder can also be used as a rotary bearing for sealing elements, the winding holder can also function as a pure deflection element.

Von besonderem Vorteil ist es nun, wenn eine Vorrichtung zum Auf- und Abwickeln von bahnenförmigen Dichtungselementen mit den Merkmalen des Schutzanspruchs 1 über einen reversierbaren Antrieb für die Wicklungshalterung verfügt. In diesem Falle kann nämlich der Antrieb der Wicklungshalterung durch den vorzugsweise hydraulisch arbeitenden Bordantrieb gebildet sein.It is particularly advantageous if a device for winding and unwinding sheet-shaped sealing elements with the features of claim 1 has a reversible drive for the winding holder. In this case, the drive of the winding holder can be formed by the preferably hydraulic on-board drive.

Insbesondere im Hinblick auf die Mobilität der erfindungsgemäßen Vorrichtung ist es vorteilhaft, wenn der Antrieb auf bzw. in der Vorrichtung integriert ist und so keine zusätzliche externe Einheit erforderlich ist.In particular with regard to the mobility of the device according to the invention, it is advantageous if the drive is integrated on or in the device and so no additional external unit is required.

In Verbindung mit dem Transportproblem der erfindungsgemäßen Vorrichtung wird darauf hingewiesen, daß die Wicklungshalterung bzw. der Umfang der Wicklungshalterung so bemessen ist, daß ein Auf- und Abwickeln von Dichtungselementen lediglich eine reversible Verformung der Dichtungselemente bewirkt. Je nach der Stärke der Dichtungselemente muß bzw. kann der Umfang der Wicklungshalterung größer oder kleiner bemessen sein. In jedem Falle ist es besonders vorteilhaft, wenn die Wicklungshalterung aus mehreren Segmenten und/oder Komponenten zusammengesetzt werden kann.In connection with the transport problem of the device according to the invention, it is pointed out that the winding holder or the circumference of the winding holder is dimensioned such that winding and unwinding of sealing elements only causes a reversible deformation of the sealing elements. Depending on the thickness of the sealing elements, the circumference of the winding holder may or may have to be larger or smaller. In any case, it is particularly advantageous if the winding holder can be composed of several segments and / or components.

In einer besonders vorteilhaften Ausgestaltung der erfindungsgemäßen Vorrichtung weist die Wicklungshalterung eine antreibbare Mittelachse auf. Vorzugsweise in den Endbereichen der Mittelachse sind zumindest zwei Haltekränze angeordnet, die über eine segmentartig zusammensetzbare Gestängeanordnung miteinander verbunden sind. Dieser Aufbau ermöglich die Realisierung einer rollen- bzw. trommelartigen Wicklungshalterung, die jedoch nicht massiv ist und daher ein vergleichsweise geringes Gewicht aufweist und die zusätzlich noch in ihrem Umfang variabel ausgestaltbar ist. Dazu können unterschiedliche Gestängeanordnungen verwendet werden.In a particularly advantageous embodiment of the device according to the invention, the winding holder has a drivable central axis. At least two retaining rings are preferably arranged in the end regions of the central axis, which are connected to one another via a linkage arrangement that can be assembled in segments. This construction enables the realization of a roll-like or drum-like winding holder, which, however, is not massive and therefore has a comparatively low weight and can also be configured with a variable scope. Different linkage arrangements can be used for this.

Besonders vorteilhaft ist es nun, wenn die Gestängeanordnung im wesentlichen aus linearen Elementen, vorzugsweise aus Stangen und/oder Rohren zusammengesetzt ist.It is particularly advantageous if the linkage arrangement is essentially composed of linear elements, preferably rods and / or tubes.

In einer bevorzugten Ausführungsform sind erste Elemente bezüglich der Mittelachse radial nach außen weisend, sternförmig an den Haltekränzen angeordnet. Der Durchmesser der Wicklungshalterung bestimmt sich im wesentlichen nach den Abmessungen dieser ersten Elemente. Die an jedem Haltekranz benachbart angeordneten ersten Elemente sind über weitere Elemente miteinander verbunden. Auch die an den beiden Haltekränzen jeweils gegenüberliegend angeordneten ersten Elemente sind über weitere Elemente miteinander verbunden. Je nach Anordnung und Dimensionierung dieser weiteren Elemente läßt sich die Breite der Wicklungsanordnung variieren.In a preferred embodiment, first elements are arranged radially outward with respect to the central axis and are arranged in a star shape on the retaining rings. The diameter of the winding holder is essentially determined by the dimensions of these first elements. The first elements arranged adjacent to each retaining ring are connected to one another via further elements. The first elements arranged opposite each other on the two retaining rings are also connected to one another via further elements. The width of the winding arrangement can be varied depending on the arrangement and dimensioning of these further elements.

In einer besonders vorteilhaften Ausgestaltung der erfindungsgemäßen Vorrichtung erfolgt die Ausrichtung des Dichtungselements über bzw. in dem Erdschlitz nicht nur durch Ausrichtung der Wicklungshalterung, sondern auch mit Hilfe einer verstellbaren Umlenkvorrichtung, die als Führung für das Dichtungselement dient und dieses beispielsweise gegen ein Trageelement drückt.In a particularly advantageous embodiment of the device according to the invention, the sealing element is aligned above or in the earth slot not only by aligning the winding holder, but also with the aid of an adjustable deflection device which serves as a guide for the sealing element and presses it against a support element, for example.

Insbesondere zum Aufwickeln bzw. Aufziehen von bahnenförmigen Dichtungselementen an einem Bearbeitungsort im Baustellenbereich ist es vorteilhaft, wenn an der Wicklungshalterung der erfindungsgemäßen Vorrichtung mindestens ein lösbar oder unlösbar angeordnetes, flexibles, bandförmiges Element vorgesehen ist, das an dem Dichtungselement befestigbar ist und auf Aufwickelhilfe dient. Das Dichtungselement muß in diesem Falle nicht manuell angehoben und über seiner Auflagefläche zu der Wicklungshalterung gezogen werden, da dies automatisch über die Drehbewegung der Wicklungshalterung erfolgt.In particular for winding or pulling web-shaped sealing elements at a processing location in the construction site area, it is advantageous if at least one detachable or non-releasable, flexible, band-shaped element is provided on the winding holder of the device according to the invention, which element can be fastened to the sealing element and is used on the winding aid. In this case, the sealing element does not have to be lifted manually and pulled over its support surface to the winding holder, since this takes place automatically via the rotary movement of the winding holder.

Das flexible, bandförmige Element kann beispielsweise durch ein Seil, eine Kette oder auch einen Gewebegurt gebildet sein. Besonders vorteilhaft ist die Verwendung von einem oder mehreren Hebebändern. Diese Hebebänder sind einerseits am Umfang der Wicklungshalterung befestigt und können andererseits im Endbereich des bahnenförmigen Dichtungselements befestigt werden. Wird die Wicklungshalterung dann angetrieben, so werden zunächst die Hebebänder aufgewickelt, wobei wiederum das Dichtungselement angehoben und zu der Wicklungshalterung gezogen wird bis es schließlich selbst auf die Wicklungshalterung aufgewickelt wird.The flexible, band-shaped element can be formed, for example, by a rope, a chain or a fabric belt. The use of one or more lifting straps is particularly advantageous. These lifting straps are attached to the circumference of the winding holder on the one hand and can be attached in the end region of the sheet-shaped sealing element on the other hand. If the winding holder is then driven, the lifting straps are first wound up, again the sealing element being raised and pulled towards the winding holder until it is finally wound onto the winding holder itself.

Es gibt nun verschiedene Möglichkeiten, die Lehre der vorliegenden Erfindung in vorteilhafterweise auszugestalten und weiterzubilden. Dazu ist einerseits auf die dem Schutzanspruch 1 nachgeordneten Ansprüchen und andererseits auf die nachfolgende Erläuterung eines Ausführungsbeispiels der Erfindung anhand der Zeichnung zu verweisen. In Verbindung mit der Erläuterung des Ausführungsbeispiels werden auch im allgemeinen bevorzugte Ausgestaltungen und Weiterbildungen der Lehre erläutert.There are now various possibilities for advantageously designing and developing the teaching of the present invention. For this purpose, reference is made on the one hand to the claims subordinate to protection claim 1 and on the other hand to the following explanation of an embodiment of the invention with reference to the drawing. In connection with the explanation of the exemplary embodiment, generally preferred configurations and developments of the teaching are also explained.

Die Figuren 1 bis 3 zeigen eine Vorrichtung zum Auf- und Abwickeln von bahnenförmigen Dichtungselementen 2, insbesondere von, mit Schlössern versehenen Folien, mit einer drehbar gelagerten Wicklungshalterung 1.FIGS. 1 to 3 show a device for winding and unwinding sheet-shaped sealing elements 2, in particular foils provided with locks, with a rotatably mounted winding holder 1.

Erfindungsgemäß ist die Vorrichtung als Fahrzeug ausgebildet und umfaßt ein Fahrwerk 3, das bei dem, in den Figuren 1 bis 3 dargestellten Ausführungsbeispiel durch das Fahrwerk eines Kettenfahrzeugs gebildet ist. Die Wicklungshalterung 1 bildet zumindest einen Teil des Oberaufbaus des Fahrzeugs. Die erfindungsgemäße Vorrichtung ist zumindest im Baustellenbereich auch zum Transport von Dichtungselementen 2 einsetzbar. Beispielsweise können einzelne Folienbahnen am sogenannten Schweißplatz, wo die Folienbahnen zugeschnitten werden und Schlösser seitlich an die Folienbahnen angeschweißt werden, auf die Wicklungshalterung aufgewickelt bzw. aufgetrommelt werden. Die gesamte Vorrichtung, d. h. das Fahrzeug mit der Wicklungshalterung als Oberaufbau, kann die Folie dann innerhalb des Baustellenbereichs zum Einsatzort transportieren, nämlich zu dem Erdschlitz, in den die Folie abgesenkt werden soll.According to the invention, the device is designed as a vehicle and comprises a chassis 3, which in the exemplary embodiment shown in FIGS. 1 to 3 is formed by the chassis of a tracked vehicle. The winding holder 1 forms at least part of the superstructure of the vehicle. The device according to the invention can also be used at least in the construction site area for the transport of sealing elements 2. For example, individual film webs can be wound or reeled onto the winding holder at the so-called welding station, where the film webs are cut and locks are welded to the side of the film webs. The entire device, i. H. the vehicle with the winding holder as the superstructure can then transport the film within the construction site area to the place of use, namely to the earth slot into which the film is to be lowered.

In dem in den Figuren 1 bis 3 dargestellten Ausführungsbeispiel ist der Oberaufbau, bzw.die Wicklungshalterung 1 des Fahrzeugs bezüglich der Position des Fahrwerks 3 horizontal verschiebbar. Dazu ist die Wicklungshalterung 1 über Träger 4 mit dem Fahrwerk 3 verbunden. Über die Träger 4 kann die Wicklungshalterung 1 nun lateral in zwei Richtungen in einer Ebene verschoben werden. In Figur 1 ist die erfindungsgemäße Vorrichtung neben einem Erdschlitz positioniert.In the exemplary embodiment illustrated in FIGS. 1 to 3, the superstructure or the winding holder 1 of the vehicle can be displaced horizontally with respect to the position of the chassis 3. For this purpose, the winding holder 1 is connected to the undercarriage 3 via the carrier 4. The winding holder 1 can now be laterally displaced in two directions in one plane via the carrier 4. In Figure 1, the device according to the invention is positioned next to an earth slot.

Mit Hilfe der Träger 4 kann die Wicklunshalterung 1 nun sowohl senkrecht zum Erdschlitz als auch parallel zu diesem Erdschlitz verschoben werden. Es ist auch möglich, die Wicklungshalterung 1 um eine vertikale Achse drehbar bezüglich dem Fahrwerk 3 zu lagern, so daß die Wicklungshalterung 1 auch bezüglich der Orientierung des Erdschlitzes verschwenkt werden kann.With the help of the carrier 4, the winding holder 1 can now be moved both perpendicular to the earth slot and parallel to this earth slot. It is also possible to mount the winding holder 1 rotatably about a vertical axis with respect to the chassis 3, so that the winding holder 1 can also be pivoted with respect to the orientation of the earth slot.

Um nun die Position der Wicklungshalterung 1 bezüglich dem Erdschlitz zu fixieren und auch um die Standfestigkeit der erfindungsgemäßen Vorrichtung zu erhöhen, sind vertikal ausfahrbare Abstützeinrichtungen 5 vorgesehen, die an den Trägern 4 angeordnet sind. Die Abstützeinrichtungen 5 in dem in den Figuren dargestellten Ausführungsbeispiel sind mit einem beweglich angelenkten, tellerförmigen Fußstück 6 ausgestattet. Hat die erfindungsgemäße Vorrichtung bzw. die Wicklungshalterung 1 ihre Zielposition erreicht, so werden die Abstützeinrichtungen 5 vertikal ausgefahren und gegen den Boden gestemmt, wobei die angelenkten Fußstücke eine Anpassung an lokale Unebenheiten ermöglichen.In order to fix the position of the winding holder 1 with respect to the earth slot and also to increase the stability of the device according to the invention, vertically extendable support devices 5 are provided which are arranged on the carriers 4. The support devices 5 in the embodiment shown in the figures are equipped with a movably articulated, plate-shaped foot piece 6. If the device according to the invention or the winding holder 1 has reached its target position, the support devices 5 are extended vertically and braced against the ground, the articulated foot pieces allowing adaptation to local unevenness.

In dem in den Figuren dargestellten Ausführungsbeispiel ist der Oberaufbau, d. h. die Wicklungshalterung 1 vom Fahrwerk 3 abnehmbar. Dies ist durch die Verbindungselemente 14 angedeutet. Die erfindungsgemäße Vorrichtung kann also zumindest in zwei Teilen zur Baustelle transportiert werden.In the embodiment shown in the figures, the superstructure, i. H. the winding bracket 1 removable from the chassis 3. This is indicated by the connecting elements 14. The device according to the invention can thus be transported to the construction site in at least two parts.

Auch die Wicklungshalterung 1 ist in dem hier dargestellten Ausführungsbeispiel aus mehreren Segmenten und Komponenten zusammengesetzt. Sie weist eine antreibbare Mittelachse 7 auf.In the exemplary embodiment shown here, the winding holder 1 is also composed of several segments and components. It has a drivable central axis 7.

In den Endbereichen der Mittelachse 7 sind Haltekränze 8 angeordnet, die über eine segmentartig zusammengesetzte Gestängeanordnung miteinander verbunden sind. Diese besteht im wesentlichen aus linearen Elementen 9 bis 11, die beispielsweise durch Stangen und/oder Rohre gebildet sind. Erste Elemente 9 sind bezüglich der Mittelachse 7 radial nach außen weisend, sternförmig an den Haltekränzen 8 angeordnet. Die an jedem Haltekranz 8 benachbart angeordneten ersten Elemente 9 sind über weitere Elemente 10 radial außen liegend miteinander verbunden, was besonders deutlich in Figur 1 dargestellt ist. Aus Figur 2 geht hervor, daß auch die an den beiden Haltekränzen 8 jeweils gegenüberliegend angeordneten ersten Elementen 9 über weitere Elemente 11 radial außen liegend miteinander verbunden sind. Diese Gestängeanordnung bildet also praktisch das Gerüst einer Rolle oder Trommel, um das ein Dichtungselement 2 gewickelt werden kann. Der Durchmesser dieser Trommel kann je nach Wahl der ersten Elemente 9 und der Anordnung der Elemente 10 variiert werden. Auch die Breite der Trommel ist variierbar, und zwar durch die Auswahl der weiteren Elemente 11. Üblicherweise wird der Umfang der Trommel so bemessen, daß ein Auf- und Abwickeln von Dichtungselementen 2 lediglich eine reversible Verformung der Dichtungselemente 2 bewirkt. Dabei kommt es weniger auf die Folienbahnen selbst an, als auf die angeschweißten, durch Kunststoffprofile gebildeten Schlösser. Eine dauerhafte Verformung dieser Schlösser würde das Aneinanderreihen und Verbinden von Dichtungselementen zu einer zusammenhängenden Dichtwandschürze unmöglich machen.Retaining rings 8 are arranged in the end regions of the central axis 7 and are connected to one another via a linkage arrangement which is composed of segments. This consists essentially of linear elements 9 to 11, which are formed for example by rods and / or tubes. First elements 9 are arranged radially outward with respect to the central axis 7, arranged in a star shape on the holding rings 8. The first elements 9 arranged adjacent to each retaining ring 8 are connected to one another radially on the outside via further elements 10, which is shown particularly clearly in FIG. 1. It can be seen from FIG. 2 that the first elements 9, which are arranged opposite each other on the two holding rings 8, are connected to one another via further elements 11, lying radially outside. This linkage arrangement thus practically forms the framework of a roller or drum, around which a sealing element 2 can be wound. The diameter of this drum can be varied depending on the choice of the first elements 9 and the arrangement of the elements 10. The width of the drum can also be varied, specifically by the selection of the further elements 11. The circumference of the drum is usually dimensioned such that winding and unwinding of sealing elements 2 only causes a reversible deformation of the sealing elements 2. It is less a question of the film web itself than of the welded locks formed by plastic profiles. A permanent deformation of these locks would make it impossible to string together and connect sealing elements to form a coherent sealing wall apron.

Die in den Figuren dargestellte erfindungsgemäße Vorrichtung weist ferner eine in ihrer Position verstellbare Umlenkvorrichtung 13 als Führung für das Dichtungslement 2 auf.The device according to the invention shown in the figures also has a deflection device 13 which is adjustable in its position as a guide for the sealing element 2.

In Figur 1 ist die Funktionsweise dieser Umlenkvorrichtung 13 dargestellt. Das Dichtungselement 2 wird während des Absenkens in den Erdschlitz von der Wicklungshalterung 1 abgetrommelt. Die Wicklunshalterung 1 ist dazu parallel neben dem Erdschlitz positioniert. Das Ausrichten des Dichtungselements 2 parallel zur Orientierung des Erdschlitzes erfolgt bereits beim Absenken. Dazu wird das Dichtungselement 2 mit Hilfe der Umlenkvorrichtung 13 und eines Trageelements 16, mit dem das Dichtunselement 2 in den Erdschlitz gedrückt wird, in eine senkrechte Position gezwungen. Die Umlenkvorrichtung 13 kann dazu beispielsweise mit einer Umlenkrolle bzw. einer Führungsrolle versehen sein.The operation of this deflection device 13 is shown in FIG. The sealing element 2 is drummed off the winding holder 1 during the lowering into the earth slot. For this purpose, the winding holder 1 is positioned parallel to the earth slot. Aligning the sealing element 2 parallel to the orientation of the earth slot takes place already when lowering. For this purpose, the sealing element 2 is forced into a vertical position with the aid of the deflection device 13 and a carrying element 16, with which the sealing element 2 is pressed into the earth slot. For this purpose, the deflection device 13 can be provided, for example, with a deflection roller or a guide roller.

Insbesondere aus der Darstellung der Figur 2 geht hervor, daß die erfindungsgemäße Vorrichtung mit einem Bordantrieb 12a, b versehen ist, der die Mittelachse 7 antreibt. Der Bordantrieb 12 a, b ist steuerbar und regelbar, so daß die Wicklungsachse 7 sowohl zu Drehungen in zwei Richtungen als auch mit unterschiedlicher Geschwindigkeit angetrieben werden kann. Auf diese Weise können zum einen Dichtungselemente automatisch auf die Wicklungsvorrichtung 1 aufgetrommelt werden. Zum anderen kann auf ein Dichtungselement, das aufgrund der Gewichtskraft des Trageelements 16 in den Erdschlitz gezogen bzw. gedrückt wird, eine regelbare Rückholkraft ausgeübt werden, die beispielsweise das Einfädeln der Schlösser von benachbarten Dichtungselementen erleichtert.It can be seen in particular from the illustration in FIG. 2 that the device according to the invention is provided with an on-board drive 12a, b which drives the central axis 7. The on-board drive 12 a, b can be controlled and regulated, so that the winding axis 7 can be driven both for rotations in two directions and at different speeds. In this way, on the one hand, sealing elements can be automatically drummed onto the winding device 1. On the other hand, a controllable return force can be exerted on a sealing element that is pulled or pressed into the earth slot due to the weight of the carrying element 16, which, for example, facilitates the threading of the locks from adjacent sealing elements.

Dieser Antrieb der Wicklungshalterung und auch der Antrieb, der eine Verschiebung der Wicklungshalterung bezüglich des Fahrwerks bewirkt, ist vorzugsweise hydraulisch realisiert.This drive of the winding holder and also the drive which causes the winding holder to be displaced with respect to the undercarriage is preferably implemented hydraulically.

Zum besseren Verständnis der Einsatzmöglichkeiten der erfindungsgemäßen Vorrichtung ist in Figur 3 dargestellt, wie ein Dichtungselement 2 in einen Erdschlitz abgesenkt wird. Dazu ist eine Hubvorrichtung 15 in Form eines Krans erforderlich, der ein Trageelement 16 senkrecht in den Erdschlitz absenkt. Das Trageelement 16 ist an seinem unteren Ende mit dem unteren Ende eines bahnenförmigen Dichtungselements 2 befestigt, welches wiederum auf eine Wicklungshalterung 1 aufgewickelt ist. Die Wicklungshalterung 1 ist neben dem Erdschlitz und parallel zu diesem positioniert. Während des Absenkens des Trageelements 16 wird das Dichtungselement 2 aufgrund der Gewichtskraft des Trageelements 16 abgetrommelt und in den Erdschlitz hinabgezogen. Für eine möglichst vertikale Ausrichtung des Dichtungselements sorgt die Umlenkvorrichtung 13. Diese drückt das Dichtungselement 2 gegen das Trageelement 16. Gleichzeitig übt die Wicklungshalterung 1 eine Rückholkraft auf das Dichtungselement 2 aus, die dazu dient, das Dichtungselement 2 möglichst gespannt zu halten und gegebenenfalls wieder aus dem Erdschlitz zu ziehen.For a better understanding of the possible uses of the device according to the invention, FIG. 3 shows how a sealing element 2 is lowered into an earth slot. This requires a lifting device 15 in the form of a crane that lowers a support element 16 vertically into the earth slot. The support element 16 is fastened at its lower end to the lower end of a web-shaped sealing element 2, which in turn is wound onto a winding holder 1. The winding holder 1 is positioned next to and parallel to the earth slot. During the lowering of the support element 16, the sealing element 2 is drummed off due to the weight of the support element 16 and pulled down into the earth slot. The deflection device 13 ensures that the sealing element is oriented as vertically as possible. This presses the sealing element 2 against the carrying element 16. At the same time, the winding holder 1 exerts a return force on the sealing element 2, which serves to keep the sealing element 2 as tight as possible and, if necessary, to exert it again to pull the earth slot.

Hinsichtlich weiterer, in den Figuren nicht gezeigter Merkmale wird auf den allgemeinen Teil der Beschreibung verwiesen.With regard to further features not shown in the figures, reference is made to the general part of the description.
